For definitions specific to steel, see EN 10079. 3.1 melt mass of homogeneous liquid metal, the product of one or more furnaces mixe

30、d in the same furnace or ladle before pouring 3.2 cast solid metal resulting from the pouring of a single melt 3.3 parent cast cast of remelting stock to be used for the production of casting 3.4 approved scrap scrap used for the production of remelting stock NOTE 1 It arises from the manufacturers

31、own production or from that of the purchaser. Scrap used for the production of castings should be restricted to runners and risers, rejected castings and heavy fettling scrap but should exclude machining chips, turnings or small particles, except those from the manufacturers own production. 2) Publi

34、shed by chemical analysis 3.7 batch batch of remelting stock consists of material of the same nominal dimensions and from the same melt 4 Wording of order The order shall clearly indicate: quantities to be supplied; dates of delivery; material standard number; delivery condition and metallurgical co

35、de of products; dimensions and tolerances or reference to an appropriate dimensional standard; product designation, when required; forwarding address; nature and type of packing, if required; surface protection, if appropriate; definition and frequency of any special tests and their retest procedure

36、s, if required. 5 Health and safety Products in the delivery condition shall fulfil the health and safety laws of the area of the country when and where it is to be delivered. A product safety data sheet shall be available. 6 Technical requirements 6.1 General The product shall be manufactured in ac

37、cordance with the requirements of the relevant material standard and the applicable requirements of this specification. A manufacturing schedule shall be established and applied in accordance with EN 2078. BS EN 4700-007:2010EN 4700-007:2010 (E) 8 Product shall satisfy the requirements of the materi

38、al standard and/or order and shall be free from irregularities prejudicial to the subsequent manufacture or use of this product. Notwithstanding previous acceptance complying with this material standard, any product that is found, at a later stage, to contain such defects shall be rejected. Unless o

39、therwise specified, the requirements in Tables 1 and 2 shall apply in conjunction with those of the relevant material standard. Table 1 relates to lines 1 to 29 (inclusive) of the material standard and Table 2 relates to lines 30 onwards in which the subline format is also used. Lines 2 to 98 may al

40、so be opened in line 100 if the material standard details specific qualification requirements. If a specific line number is not shown in Tables 1 and 2, the requirement is stated in the material standard and/or order. The requirements of the order and/or material standard shall over-ride the require

41、ments of the technical specification. 6.2 Qualification requirements Qualification requirements when invoked by the material standard and/or order are detailed in Tables 1 and 2. Unless otherwise agreed between the manufacturer and purchaser the qualification phase shall be run on the first three ba

42、tches, coming from at least two casts. 6.3 Release requirements 6.3.1 Release tests Release testing shall be the responsibility of the manufacturer. The purchaser reserves the right to perform any of the inspections and/or tests required by the material standard and/or order. The test samples shall

43、be representative of the product. When required on the order, the manufacturer shall inform the purchaser of the planned dates for extraction of samples and release testing in order that these operations may be witnessed. Tables 1 and 2 detail the requirements for each line of the material standard.

44、 Unless otherwise specifically requested by the purchaser, a particular inspection and/or test for release shall be carried out if corresponding acceptance criteria and/or values are stated in the applicable material standard, but see also 6.3.5. 6.3.2 Retests If any requirement is not met, retests

45、shall be carried out under the following conditions unless otherwise stated in the material standard or order. If the test procedure or test piece preparation is faulty, testing shall be re-applied at the original frequency after rectification of the original cause of failure, on a test sample locat

46、ed near the first one. When failure cannot be attributed to faulty testing, or test piece preparation, further test samples shall be selected at twice the original frequency from the product, one of which shall be that on which the original results were obtained unless already withdrawn by the manuf

47、acturer after suitable identification of the cause of failure. If all retest results are satisfactory, the batch shall be accepted. If one or more tests are unsatisfactory, the batch shall be: rejected; or 100 % retested and the conforming products accepted; or BS EN 4700-007:2010EN 4700-007:2010 (E

48、) 9 partially or fully re-heat treated if heat treatment can rectify the cause of the failure and tested as a completely new batch except for chemical composition and cleanness inspection. The reheat treatment shall be stated on the release test certificate. For cleanness inspection, if the material

49、 fails the requirement the product may be cut back before retesting. 6.3.3 Rejection Any failure to meet the requirements of the material standard shall be cause for rejection. 6.3.4 Special tests Special tests may be required by the purchaser. In such cases, the nature of the test, method, frequency and technical requirements shall be specified on the order or inspection schedule and shall be mutually agreed by the man
